Without A Pressure Pot? Part 2

Here is a link to a downloadable PDF file with a list of the rubber, resins and waxes I use in my videos: www.dropbox.com/s/kz6mhmf7v5vpy7l/Material%20and%2…

Robert, I'm a professional designer (visual and product) and im completely blown away at the amount of knowledge you share with us. This is literally the knowledge that i paid tens of thousands of dollars for in college, and with your videos i have the ability to watch them over and over. Its incredible. Your videos are a gift for us makers.

I just started watching your videos and I have to say you are not only very knowledgeable and helpful but also I love your demeanor - you’re seem friendly and of a good humor. Thanks for what you do

Huge fan of your videos Robert, but this one was exceptional. Seeing the problems that even a veteran like yourself has to overcome makes me feel like maybe I'm not such an idiot after all. Thanks so much for sharing :)

Speaking of bubbles, how about a video on your methods for filling bubble holes?

You talked a lot about "filling in the bubbles"... can you show us how to do that?!?!?

Amazing videos. Never cast a single thing but feeling confident enough to start . Thank you Sir.

Watching you make those airfoil shaped side plates has me wanting to make a cardboard aeroplane! Great demo!

Love your videos, you're really great at explaining and funny too! May have to try mold making at some point! 😊

I used to make small runs of dice and had some of these issues. Bubbles are a plague! I finally found a solution that works for me. Precise volume measuring and non-bubble mixing can be done with syringes. Cups not so much. A pair of 60cc syringes can be bought at your local Tap Plastic or similar for under $10. To get your quarter cup, with no bubbles, you'd draw 30cc of A into one, 30cc of B into the other. To mix them with no bubbles use a tiny piece of plastic tubing that fits on their tapered noses. Put it on one of the syringes, push the contents out to completely filll the tube, and then stick the nose of the other syringe into the tube. After that you can push them back and forth from one syringe to the other through the tubing. They get thoroughly mixed with no bubbles. Then comes pouring. In both mold making and resin injection for the piece, using a tube (or "anti-sprue") and injecting all the way at the bottom is the winning move. Cavities in the piece can still catch air bubbles, but at least you're not pushing them in or covering them deeper when you pour.

You are such an inspiration for me just to keep doing and experimenting. Thank you so much !

When I was resin casting GI Joe parts, I would actually use a syringe plunger with a blunt needle. I would load it with resin, push the blunt needle down into the mold and inject the resin. I would keep injecting until it overflowed from the vent hole. This helped rinse out the air bubbles!

Great work Robert you didn’t Duck the issue of trying to get a perfect cast. I share your frustration at not having the preferred tools at your disposal. Looking forward to your next challenge.

Excellent thanks for the great video, learnt a ton

So clear example. Excelent good! Thanks!

This was a great set of videos! Very informative, I've learned so much :-)

Truly excellent videos. Have helped me a lot. Thank you so much

I like how you said “we’re not making cabinetry” in cabinetry we often say “it’s fine, we’re not making pianos” haha

Another very good video! Thanksba lot! Can't wait to make my own cast!

Excellent Video
